Autor: Agustín María de Wysiecki, Alejo Joaquin Irigoyen, Nelson D. Bovcon, Gastón Andres Trobbiani

Publikováno v: Ecología Austral. 31:170-181

Baited Remote Underwater Video Stations (BRUVS) complemented with fishing methods were used to describe the fish assemblage and its seasonal pattern in two marine inlets from Patagonia. The combined results for BRUVS and fishing sessions identified 1

Habitat use, seasonality and demography of the broadnose sevengill shark Notorynchus cepedianus in central Patagonia: Another piece of the puzzle

Autor: Nelson D. Bovcon, Gastón Andres Trobbiani, Federico Argemi, A. J. Jaureguizar, Agustín María de Wysiecki, Alejo Joaquin Irigoyen

Publikováno v: Austral Ecology. 44:1463-1470

The habitat use, seasonality and demography of the broadnose sevengill shark Notorynchus cepedianus were investigated in central Patagonia, where a data gap exists for the species. Catch and effort and video‐derived indices indicated high relative

Publikováno v: Austral Ecology. 44:397-408

The amount of energy an animal uses to move may constitute a significant fraction of its energy budget, so detailed descriptions of wild animal activity budgets can help to understand the ecology of a species, both at the individual and at the popula

Low-cost non-scientific echosounders are commonly used for safety and other non-scientific purposes. These echosounders routinely record data which are rarely processed for later use, but which could provide interesting information about the seabed.

Stable isotopes reveal different dependencies on benthic and pelagic pathways between Munida gregaria ecotypes

Autor: David Edgardo Galvan, Manuela Funes, Alejo Joaquin Irigoyen, Gastón Andres Trobbiani

Forage species are key nodes in the energy fluxes between benthic and pelagic zones. The squat lobster, Munida gregaria, is a common forage species of the Southern Hemisphere and its abundance is increasing. This species presents two ecotypes: one (s

A low-cost towed video camera system for underwater surveys: comparative performance with standard methodology

Autor: Alejo Joaquin Irigoyen, Leonardo Ariel Venerus, P. M. Fiorda, Ana M. Parma, Gastón Andres Trobbiani

Publikováno v: Environmental Monitoring and Assessment. 190

Technological advances in the field of underwater video have led to an exponential increase in the use of drifting cameras (DC) and remotely operated vehicles (ROVs) to monitor the diversity, abundance, and size structure of marine life. Main advanta

Gaining insight on how species relate to their environment and other members of the trophic community is critical for their management. We investigated habitat use, seasonal patterns of abundance and population structure of the broadnose sevengill sh

Underwater visual census (UVC) is the most common approach for estimating diversity, abundance and size of reef fishes in shallow and clear waters. Abundance estimation through UVC is particularly problematic in species occurring at low densities and

Extreme roll angles in Argentine sea bass: Could refuge ease posture and buoyancy control of marine coastal fishes?

Autor: Serena Wright, Adrian C. Gleiss, Javier Ciancio, Gastón Andres Trobbiani, Leonardo Ariel Venerus, Brad Norman, Lucas E. Beltramino, Rory P. Wilson, Mark D. Holton

The swim bladder provides a mechanism for buoyancy regulation in teleosts. However, in certain species, its location can result in an unstable body position, with associated energetic costs assumed for maintaining posture in addition to the energetic
